Cover letter [PATCH v2 0/2] x86_64: Sigcontext improvements
Patch 1 is IMO a bug fix.
Patch 2 is a cleanup and avoids some confusion. It's also sort of an API break (no ABI change) because it removes a struct field. But that struct field has never done anything at all as far as I can tell.
AFAICT this series got bogged down in discussion about patch 2 last time. I'm only including patch 2 for completeness here -- patch 1 is IMO far more useful, and I'm fine with patch 1 being merged and tabling patch 2 again.
Changes from v1:
- Add the __USER_DS fix, caught by my sigreturn test.
- Re-tested locally.
